Table 9--Chemical analyses of water from selected wells. Analyses by Kansas Department of Health and Environment, except as indicated. Dissolved constituents and hardness given in milligrams per liter (mg/L) or micrograms per liter (µg/L); specific conductance in micromho per centimeter at 25°C (µmho/cm at 25°C); depth of well given in ft below land surface. Geologic source--Kd, Dakota Formation; Kch, Cheyenne Sandstone; and Pu, undifferentiated Permian rocks. SAR, sodium-adsorption ratio.
